ELECTRIC PUSH-BUTTON FIXTURE.

- of New York city, borough of Bronx, in the county of New York and State of New York, have invented certain new and useful Improvements in Electric Push-Button Fixtures. of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a switch adapted as a single instrument for operating a plurality of signals; to provide'means for insuring the accurate selection of the distant signal operated; and to simplify and cheapen the construction.

Drawings.

Figure 1 is a perspective view of the box body cover and selection disk with which the improved switch is provided, the cover being shown as removed and partly cut away to disclose the structure of the index disk.

Fig. 2 shows the reverse face of the cover.

Fig. 3 is a cross section of the switch showing schematically, in connection therewith, the signals tobe operated by the switch and the electric supply for the operating circuit.

Fig. 4 is a view similar to Fig. 1, show- 7 ing a modified form of the invention.

Fig. 5 is a reverse view of the cover of the modified form shown in Fig. 1.

Fig. 6 is a section of the construction shown in Fig. 4:, disclosing schematically therewith, signals operated thereby, and an electric source for the operating circuit.

Description.

The switch herein disclosed is used principally in connection with the telephone switch-boards generally employed in the apartment houses where universal operating stations are provided throughout the house as distinguished from individual service provided in the individual apartments or rooms, thus, for illustration, a six-storied apartment house would be provided with a telephone switch-board and five extensions, the extensions each having an instrument at some convenient position, such as the hall where all of the occupants on any floor could use a telephone located in the hall. For incoming calls, however, it is necessary to advise the individual occupants or tenants, and to this end each tenancy has a sig- Specification of Letters letent.

na'l such as the-bells 11, as shown in the drawings; All of the bells are operatively connected with a ground wire 12 which suppliesi the various signals from the battery 13 g the battery is connected bya lead 14. with a binding-post 15 of the metal cover 16; The various signals 11 are each connected by means ofthe binding-posts 17 with one of the contact buttons 18, all of which are mounted on the electric insulating slab 19. The slab 19 in the preferred form of the invention shown in Figs. 1 to 3 inclusive, forms the bottom of the box having the sides 20. The box thus formed is permanently inclosed by the cover16, the cover 16 is provided with a view opening 21 in the center of which is a pointer 22, under which may be disposed the various indicia 23, which correspond with the various rooms or apartments occupied by individual tenants. The indicia 23 are preferably imprinted on a disk 24; the disk 24 is pivotally mounted by means of a short boss 25. which extends through a perforation suitably provided in the cover 16; the boss 25 is tubular, the passage therethrough forming a guide for the push-pin 26. V

The push pin 26 has a head'27 which is reciprocatively mounted in a socket 28, and is supported therein by a spring 29 which normally extends the button to a position where the exposed surface thereof conforms with the surface of the handle 30. The button 27, and pin 26 are limited in their movement, by a small pin 31, driven through the inner end of the push-pin 26, after the said push pin is disposed in service relation to the boss 25 and disk 24L. The handle 30 has a socketed extension, the socket wherein fits the boss 25, and is held thereon by a setscrew 32. Pivotally supported by a pin 33 at the inner side of the disk 24 is a rocking arm 34;. The free end of the arm at is normally maintained in juxtaposed relation to the disk 24 with the wiper 35, held away from, and out of contact with, the buttons 18. This position of the arm 34 is secured by the spring 36 which extends between the disk 24:, or member structurally connected therewith, and the short end of the arm 3st, said spring being preferably rigidly connected with either part of the construction. The long or free end of the arm is guided in its action by the loop 37.

The indicia 23 and the buttons 18 are so disposed with relation to the arm 34 and the wiper 35 connected therewith that when any index appears in the view-opening 21, opposite the pointer 22, the wiper 35 rests above the button 18, electrically connected with the particular signal 11 in the apartment or room corresponding to the index. When the operator moves the disk 24 so that the index shown corresponds with the room or apartment he desires to call, he pushes the button 27, and the push-pin 26 con nected therewith to press upon and rock the arm 34 until the Wiper 35 makes contact with the button 18. In this position the electric circuit in which is incorporated the particular signal 11 desired, is completed, and the tenant is thereby notified that he'or she is wanted at the telephone in the hall or predetermined location.

It is obvious that with such an installation, time and money are saved, and the convenience of operating the telephone system in buildings of the character mentioned is simplified and greater eiiiciency thereby is secured.

In the modified form of the invention shown in Figs. at to 6 inclusive, the disk 24 is dispensed with and an arm 38 is pivotally connected by a pin 39 with the cover 40 which in this case is preferably constructed from metal and is box-like in form.

The cover 40 is furnished with an arcuate slot 41, through which extends the boss 25 in which is mounted the push-pin 26. The push-pin 26 in the modified form presses upon a spring leaf 42 until the free end thereof contacts with one of the buttons 18. The pointer 43 is used for placing the arm 38 in relation to the various indicia 44 which indicate stations having correspondence with the various buttons 18.

The modified form being described, the base 4:") is constructed from suitable electric insulating material and the battery 13 and lead 14 therefrom are connected to the binding-post 4L6, which in turn is electrically connected with a metal plate 47 on the inside of the box. The short end of the leaf 42 is bent down to form a constant contact with the plate 47. The operation of the modified form is, to all intents and purposes, the same as that described with reference to the preferred form.

Claim.

A selective circuit closer comprising a plurality of annularly arranged contact buttons; a cover plate for said buttons; a disk rotatively mounted in said cover plate, said disk having an open-ended tubular boss, forming a bearing for said disk, said disk being provided with indicia markings, said markings being arranged for successive exposure through an opening in said cover plate; a tubular handle removably mounted on said boss for operating said disk; a rocking arm pivotal-1y suspended on said disk and extended in parallel relation to a diameter thereof, the free end of said arm extending into a path coincident with said buttons; and a reciprocating push-pin mounted in said handle and resting on said arm for depressing the free end thereof to engage said buttons successivel OSCAR A.
